N/A

AN INNOVATIVE ELECTRODE DESIGN FOR ELECTROSTATIC PRECIPITATORS THAT WILL ENHANCE FINE PAARTICLE COLLECTION HAS BEEN DEVELOPED. THIS NEW DESIGN CONCEPT INVOLVES WAVE-SHAPED ELECTRODES (WAVY ELECTRODES) AND OFFERS SOME FUNDAMENTAL IMPROVEMENTS OVER THE CONVENTIONAL PRECIPITATOR CONFIGURATION. IN TERMS OF THE ELECTRIC FIELD AND GAS FLOW CHARACTERISTICS, THE IMPROVEMENTS ARE (1) A MORE UNIFORM ELECTRI ...

N/A

THIS RESEARCH WILL EXPLORE THE POSSIBILITIES AND RESULT IN THE DESIGN OF AN ACOUSTIC ENERGY GENERATOR FOR GEOPHYSICAL EXPLORATION IN INACCESSIBLE MOUNTAINOUS TERRAIN. THIS EFFORT WILL DETERMINE THE MAGNITUDE OF ACOUSTIC SIGNAL REQUIRED AND WILL DEVELOP A TECHNIQUE FOR COUPLING THE SIGNAL GENERATOR TO THE EARTH. THE COUPLING TECHNIQUE WILL EXAMINE FORCES OTHER THAN GRAVITY TO ENSURE THAT THE SIGNAL ...

N/A

THE CONCEPTUAL DESIGN OF A MAN-PORTABLE GAS CHROMATOGRAPH MASS SPECTROMETER (GCMS) IS OUTLINED, TOGETHER WITH ITS APPLICATION AS A DETECTOR OF A BROAD RANGE OF HAZARDOUS ENERGY-RELATED SUBSTANCES. THE PRINCIPAL BENEFITS OF SUCH AN INSTRUMENT ARE ITS PORTABILITY WHICH ALLOWS MEASUREMENTS TO BE MADE ON-SITE, ITS RUGGED, SIMPLE OPERATION, AND ITS SENSITIVITY AND ABILITY TO GIVE UNAMBIGUOUS IDENTIFICA ...

AN ON-LOAD TAP CHANGER ALLOWS CHANGING TAPS WITHOUT INTERRUPTING POWER TO THE LOAD. CURRENTLY AVAILABLE TAP CHANGER FOR THIS APPLICATION ARE MECHANICAL TYPE WITH CONTACTS THAT ARC AND PIT EVERY TIME A CHANGE IS MADE. SOLID STATE TAP CHANGER WOULD OVERCOME THESE SHORTCOMINGS IN ADDITION WOULD ALLOW REMOTE TAP CHANGING, INTEGRATING TAP CHANGING IN PROCESS CONTROL SYSTEM, READILY CHANGE THE TAPS TO S ...

ELIMINATION OF SULFUR CONTAMINANTS FROM HOT COAL GAS AND THEIR SUBSEQUENT REDUCTION OR DISPOSALIS AN ESSENTIAL STEP FOR THE VIABLE APPLICATION OF ADVANCED COAL CONVERSION TECHNOLOGIES, SUCH AS INTEGRATED GASIFICATION COMBINED CYCLE STYSTEMS. MIXED METAL OXIDE SORBENT BEDS HAVE BEEN SHOWN TO BE VERY EFFECTIVE FOR HOT FUEL GAS CLEANUP WITH OVERALL SULFUR REMOVAL EFFICIENCIES EXCEEDING 95%. HOT OFF G ...

A MICRO-PULSE ELECTRON GUN THAT APPEARS CAPABLE OF PEAK CURRENTS OF ABOUT 10 KA WITH A MICRO-PULSE LENGTH OF SEVERAL PICOSECONDS (PS) OCCURING AT FREQUENCIES OF UP TO 10 GHZ IS BEING PLANNED. THE MICRO-PULSES OR BUNCHES ARE PRODUCED BY RESONANTLY AMPLIFYING A CURRENT OF SECONDARY ELECTRONS IN A RADIO FREQUENCY (RF) CAVITY. BUNCHING OCCURS RAPIDLY AND IS FOLLOWED BY SATURATION OF THE CURRENT DENSIT ...

THIS PROJECT INVOLVES THE ANALYSIS OF A HIGH HARMONIC, HIGH EFFICIENCY MICROWAVE GENERATOR THAT APPEARS TO BE SUITABLE FOR APPLICATIONS SUCH AS A DRIVER FOR THE NEXT GENERATION OF LINEAR COLLIDERS. THE CONCEPT EMPLOYS A ROTATING "SPIRALING" BEAM TO EXCITE AND AMPLIFY CIRCULARLY POLARIZED MICROWARE RADIATION IN AN INTERACTION OUTPUT WAVEGUIDE. MODULATION OF A LINEAR, HIGH POWER, SMALL DIAMETER BEAM ...
